Autism Glossary (A–Z)

Clear, respectful definitions — explained in everyday language.

Welcome

Words that honour autistic experiences

This glossary gathers common terms used when talking about autism — with language that aims to be clear, kind, and respectful.

Note: Autism is a natural form of human neurodiversity. People prefer different language (identity-first or person-first). This page offers learning support — not strict rules.

Go at your own pace

Some terms may feel personal. You can take breaks, skip sections, or come back later. There is no “wrong” way to use this page.

Tip: Search filters the definitions live as you type.

Gentle note: This glossary includes words connected to sensory overload, shutdowns, burnout, and support needs. Everything is written in calm, non-judgemental language. If anything feels heavy, it’s okay to pause.

Support & accommodations

Helpful supports (school, work, everyday life)

These are examples you can adapt — not a checklist you “must” follow.

Sensory supports: headphones, sunglasses, fidgets, scent-free options, predictable lighting.
Communication supports: written instructions, extra processing time, clear expectations, option to message instead of call.
Routine supports: visual schedules, reminders, “what to expect” notes, step-by-step checklists.
Regulation supports: quiet breaks, movement breaks, access to a calm space, co-regulation (supportive person nearby).
Learning supports: chunked tasks, reduced copying, alternative ways to show learning (oral, video, practical, project-based).

NZ-friendly note: If you’re in Aotearoa New Zealand, support may involve your school’s learning support team, learning support coordinators, and (where appropriate) formal planning like an IEP. You can also ask your GP or local services about assessment pathways and support options.

Letter A

Autism: A neurotype (a way of thinking, sensing, and processing) that can shape communication, social interaction, interests, and sensory experiences. Example: “My autism means I notice patterns others miss, and I can get overwhelmed by loud noise.”
Alexithymia: Difficulty identifying, describing, or noticing emotions in yourself (and sometimes others). It’s not a lack of feelings. Example: “I know something is ‘off’ in my body, but it takes time to name the emotion.”
Accommodation: A change to the environment or expectations so a person can access learning, work, or daily life more fairly. Example: “I use written instructions and noise-cancelling headphones as accommodations.”

Letter B

Burnout (Autistic burnout): Deep exhaustion and reduced capacity after long-term stress, masking, overload, or lack of support — often lasting weeks or months. Example: “After months of pushing through, I hit burnout and needed real rest and fewer demands.”
Body cues: Signals from your body that tell you what you need (hunger, tension, fatigue, sensory overload). Example: “When my jaw tightens, it’s a cue I need a break.”

Letter C

Co-regulation: When a supportive person helps you settle your nervous system through calm presence, reassurance, or practical help. Example: “Sitting quietly with me helps me regulate faster than lots of talking.”
Communication differences: Differences in how someone communicates (direct speech, fewer facial expressions, scripting, needing extra time). Example: “I’m not ignoring you — I’m processing and will reply in a minute.”
Comfort item: An item that supports regulation or safety (fidget, soft fabric, hoodie, weighted item). Example: “Holding my fidget helps me focus in meetings.”

Letter D

Demand avoidance: When demands feel overwhelming or threatening to autonomy, and the nervous system reacts by avoiding or resisting. Example: “If it feels urgent or pressured, my brain locks — I do better with choices and time.”
Dysregulation: When emotions, energy, or sensory input become too much and it’s harder to cope or function. Example: “After the noisy event, I was dysregulated and needed quiet.”

Letter E

Executive functioning: Skills that help you start tasks, plan, switch focus, remember steps, and manage time and energy. Example: “I can understand the task, but starting it is the hard part.”
Equal access: Making sure everyone can participate with appropriate supports (not “special treatment”). Example: “A quiet room option gives equal access to the event.”

Letter F

Fixation / Special interest: A deep, focused interest that can bring joy, comfort, learning, and regulation. Example: “My special interest helps me recover after stressful days.”
Flight / fight / freeze: Nervous system survival responses that can show up during overload or perceived threat. Example: “When overwhelmed, I freeze and can’t speak.”

Letter G

Gestalt language processing: Learning language in chunks/phrases (scripts) before breaking them into smaller parts. Example: “I use familiar phrases to communicate when I’m tired.”
Grounding: A way to return to the present moment using senses and gentle attention. Example: “I name five things I can see to help my body settle.”

Letter H

Hyperfocus: Deep concentration on one thing, sometimes losing track of time or needs. Example: “I hyperfocused and forgot to eat — reminders help.”
Hypersensitivity: Being extra sensitive to sensory input (sound, light, touch, smell). Example: “Bright lights feel painful, so I use sunglasses indoors.”

Letter I

Interoception: Sensing internal body signals like hunger, thirst, pain, temperature, or emotions in the body. Example: “I don’t notice I’m hungry until I feel shaky.”
Inclusive communication: Communication that supports different processing needs (clear, direct, written options). Example: “Please send the details in writing — it helps me plan.”

Letter J

Judgement-free language: Words that describe without shaming (e.g., “support needs” instead of “difficult”). Example: “I’m not ‘too sensitive’ — my nervous system processes input strongly.”

Letter K

Kind support: Support that respects autonomy, consent, and dignity (asking, not forcing). Example: “Do you want help, space, or a quiet option?”

Letter L

Literal processing: Preferring clear, exact wording; figurative language can be confusing without context. Example: “I do better with ‘meet at 3pm’ than ‘see you later’.”
Low-demand approach: Reducing pressure and demands to support safety, regulation, and capacity. Example: “When I’m overloaded, fewer choices and less urgency helps.”

Letter M

Masking: Hiding or changing autistic traits to fit in or avoid negative reactions — often exhausting. Example: “I can ‘seem fine’ while masking, but it drains me.”
Meltdown: An intense response to overload (sensory, emotional, demand) where control becomes harder. Example: “After too much noise, I had a meltdown — I needed space and time.”

Letter N

Nervous system: The body’s safety system that detects stress and helps you respond (calm, alert, overwhelmed). Example: “My nervous system goes into high alert in busy supermarkets.”
Neurodiversity: The idea that human brains vary naturally (autism, ADHD, dyslexia, etc.) and these differences matter. Example: “Neurodiversity means there isn’t one ‘right’ brain type.”

Letter O

Overload (sensory overload): When sensory input becomes too intense and the body struggles to cope. Example: “The lights + noise + crowds stacked up into overload.”
Order / predictability: Feeling safer when routines and expectations are clear. Example: “A schedule helps me feel calm and prepared.”

Letter P

Processing time: Extra time needed to understand information and respond. Example: “If you pause after asking, I can answer more clearly.”
Preference-based support: Support that matches what the person finds helpful (not what others assume). Example: “I prefer written prompts, not surprise questions.”

Letter Q

Quiet space: A calmer environment used to reduce overload and support regulation. Example: “A quiet room helped me reset and rejoin later.”

Letter R

Regulation: Keeping emotions, energy, and sensory input within a manageable range. Example: “Movement breaks help me regulate.”
Routine: Predictable steps that reduce uncertainty and support wellbeing. Example: “My routine helps mornings feel less stressful.”

Letter S

Shutdown: A response to overload where the body “powers down” — reduced speech, movement, or interaction. Example: “After the event, I shutdown and needed quiet with no questions.”
Stimming: Self-stimulatory movement or sound that helps regulate (rocking, tapping, humming). Example: “Stimming helps my body feel steady.”
Sensory seeking: Craving sensory input (movement, pressure, texture) for regulation or enjoyment. Example: “I like weighted blankets because pressure helps me settle.”

Letter T

Transition: Moving from one task/place/state to another — can be difficult without warning or structure. Example: “I need a 5-minute warning before switching tasks.”
Trust-building: Safety grows when people are consistent, clear, and respectful. Example: “When people keep their word, I feel safer.”

Letter U

Unmasking: Letting autistic traits show more openly (often in safe environments), rather than constantly performing. Example: “Unmasking at home helps me recover.”

Letter V

Validation: Being taken seriously and respected, even when others don’t share your experience. Example: “Thank you for believing me — that helped.”
Visual supports: Pictures, icons, schedules, or written steps that reduce processing load and support independence. Example: “A visual checklist helps me remember the routine.”

Letter W

Wellbeing supports: Supports that protect energy, reduce overwhelm, and build a sustainable life. Example: “My wellbeing plan includes quiet time after social events.”

Letter X

X-factor (individual differences): A reminder that autistic experiences vary widely — supports should be personalised. Example: “What helps one autistic person may not help another — we tailor it.”

Letter Y

Your way is valid: A strengths-based reminder: needs and supports are not failures — they are information. Example: “Needing headphones isn’t dramatic — it’s self-support.”

Letter Z

Zone of regulation: A way to describe your current state (calm, alert, overloaded) so supports can match your needs. Example: “I’m in the ‘too much’ zone — I need quiet and less talk.”
